This section describes a data view that routes all requests to a data source pool, irrespective of the target DN of the request. This data view is called the root data view. The root data view is created by default when an instance of Directory Proxy Server is created.
The example in this section has multiple data sources that contain the same set of subtrees. The data sources are data-equivalent and pooled into one data source pool for load balancing. A data view is configured with a base DN at the rootDSE, represented as “ ”. Figure 17–3 shows an example deployment.
Because the base DN of the data view is the rootDSE, the data view encompasses the base DN of all possible requests. All requests are forwarded to the data source pool, irrespective of the target DN or whether the data source contains an entry for the request.
If Directory Proxy Server receives a request with a target DN that does not exist in the data source, the request is forwarded to the data source pool. The data source that responds to the request returns an error.
For information about how to configure the data view in Figure 17–3, see Data Views That Route All Requests, Irrespective of the Target DN of the Request in Sun Java System Directory Server Enterprise Edition 6.3 Administration Guide.
